White Castle Slides Into Food-Truck Trend - Businessweek: White Castle is getting ready to serve its square-shaped sliders on wheels with the planned launch later this month of two food trucks in Louisville, Ky., and Columbus, Ohio, where the company is based. The so-called CraveMobiles will be available only for events at first—that includes weddings, in case either Harold or Kumar are planning to tie the knot—while company officials determine exactly where the trucks will be stationed, says Jamie Richardson, a White Castle vice president. Once regular locations are mapped out, the trucks will likely stay open 24 hours, just like almost all of White Castle’s brick-and-mortar stores. Richardson says the food-truck menu, although not yet finalized, will include three variations on the chain’s signature sliders and might see items not available in stores, such as salty caramel fries.
